ELI E. HENDRIGK, OF NEW YORK, N; Y.

- Specification forming part of Letters Patent No. 35,754, dated July 1,1862 To all whom it may concern:

Be it known that I, ELI E. HENDRrcK, of New York, in the State of NewYork, have invented a new and useful lubricating compound for thepurpose of lubricating the bearings or journals of machinery; and I dohereby declare that the following is a full,-clear, and exactdescription of the same, reference. being bad to the accompanyingspecimens and the letters of reference marked thereon.

To enable others skilled in the art to make and use my invention, I willproceed to describe its composition and the manner of compounding thesame.

1 dissolve one ounce (more or less) of caoutchouc (see specimen markedD) in one gallon of the substance known as coal-oil, rockoil, also aspetroleum, either crude or refined, manufactured or natural. (Seespecimen marked E.) I then add to this solution (see specimen marked F)an equal quantity of wa ter. (See specimenmarked G.) I violently agitatethe whole by stirring shaking, or otherwise until a union of theingredients takes place,forming a mueilaginous compound. (See specimenmarked H.) The compound is then ready for use for the purpose oflubricating the hearings or journals of machinery in like manner andproportion as other oil.

I do not confine myself to dissolving the caoutchoucin the coal-oilused, for the reason that nearly as good results will be attained bydissolving the caoutchouc in any other solvent of that gum and thenmixing such solvent with the coal-oil, the superior lubricatingproperties ot'my compound being in a great measure due to the caoutchoucused, and the solvent compound also possessing the peculiar property ofcausing the oily substance to unite with the. water. J. thereforedescribe. lay-int: vention as consisting in com ounding Ga-01kt" ehouewith coal-oil or other substance as a solvent for the caoutchouc, andthen'mixing such compound with coal-oil and Water to constitute the mainbulk of the fluid for lubricating the bearings or journals of machinery.

I do not confine myself to any specific amounts of either of thecomponent parts of the compound described, but find those named toanswer an excellent purpose.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is--- The use of asolution of caoutchouc in connection with coal-oil and watersubstantially in the manner and for the purpose set forth.
